Can you use the travel bank on partners? That would surprise me a little.

What's "Best" is whatever you want to spend the money on. Vacations packages are a flight and a hotel and/or car. If you want to go to the destination and stay at the hotel and it is cheaper than booking separately then it is a good deal. If not, it is not.

I think Mint is generally a great value for the price, but that doesn't always make it the best deal.
